ABSTRACT:
Methods and apparatus are provided for soft decision decoding using reliability values based on a log base two function. A signal is processed to determine one or more reliability values for a soft decision decoder by computing one or more log-likelihood ratio (LLR) values using a log base two function. The soft decision decoder may employ, for example, a belief propagation algorithm. The soft decision decoder can decode, for example, Low-Density Parity Check codes or turbo codes.
